Description

Technical Field

[0001] This utility model belongs to the field of motor technology, and relates to a stator and rotor, and particularly to a water-cooled stator and rotor. Background Technology

[0002] The stator and rotor, also known as the stationary rotor, are among the key components of an electric motor. Their characteristics and functions have a significant impact on the overall performance of the motor. The effect of temperature on motor efficiency is mainly reflected in the copper losses of the stator and rotor. As the temperature increases, the DC resistance of the stator or rotor windings increases. The higher the temperature, the greater the resistance, and the greater the loss for the same current.

[0003] Traditional stators and rotors increase their heat dissipation efficiency by increasing the contact area with air through structures such as heat sinks. However, air has a low heat capacity and poor heat dissipation efficiency, so it is necessary to develop stators and rotors with higher heat dissipation efficiency. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a water-cooled stator and rotor with high-efficiency heat dissipation.

[0005] The objective of this utility model can be achieved through the following technical solution: A water-cooled stator and rotor, characterized in that it includes a stator and a rotor, the stator is provided with a mounting housing, one side of the mounting housing is provided with an annular opening, the two sides of the opening are respectively provided with an outer shell part and an inner support part, the rotor is provided with a drive shaft, the drive shaft is provided with a plurality of connecting rods evenly distributed in an annular shape, the end of the connecting rod is provided with a mounting rod horizontally, and the end of the mounting rod is provided with a baffle plate, the opening is provided with two concentrically arranged bearings A and B, and a sealing plate is provided at the bearings A and B.

[0006] In the aforementioned water-cooled stator and rotor, an injection hole and a drainage hole are provided on the outer side of the outer casing.

[0007] In the aforementioned water-cooled stator and rotor, several heat dissipation spokes are evenly distributed in the inner support portion.

[0008] In the aforementioned water-cooled stator and rotor, the drive shaft is provided with several support bearings.

[0009] In the aforementioned water-cooled stator and rotor, several recessed holes are also provided on the inner wall of the inner support portion.

[0010] Compared with existing technologies, this water-cooled stator and rotor uses a disturbance plate to carry water from a lower position to a higher position, absorbing heat from the stator and reducing thermal decay of the stator and rotor. A sealing plate is installed between the bearings to prevent liquid from flowing out, and the evenly distributed heat dissipation spokes increase the efficiency of heat exchange.

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1 , 2 As shown in Figure 3, the water-cooled stator and rotor 4 includes a stator 2 and a rotor 4. The stator 2 is provided with a mounting housing 1. An annular opening 13 is provided on one side of the mounting housing 1. An outer shell 15 and an inner support 14 are respectively provided on both sides of the opening 13. The rotor 4 is provided with a drive shaft 5. Several connecting rods 12 are evenly distributed in an annular pattern on the drive shaft 5. A mounting rod 9 is horizontally provided at the end of the connecting rod 12, and a baffle 11 is provided at the end of the mounting rod 9. Two concentric bearings A3 and B6 are provided at the opening 13. A sealing plate 10 is provided at the bearings A3 and B6. Cooling liquid is provided in the opening 13. The drive shaft 5 rotates to drive the connecting rods 12, and in turn drives the mounting rods 9 and the baffle 11 in sequence. The sealing plate 10 rotates with the mounting rods 9. The baffle 11 continuously and uninterruptedly drives the liquid to a higher position, and contacts the inner support 14 to absorb heat.

[0017] Preferably, an injection hole 16 and a drainage hole 18 are provided on the outer side of the outer casing 15.

[0018] Preferably, a plurality of heat dissipation spokes 8 are evenly distributed in the inner support portion 14. The heat dissipation spokes 8 increase the efficiency of heat exchange, and at the same time, the coolant flows out through the space between the heat dissipation spokes 8, reducing the amount of liquid being shaken and thus reducing vibration.

[0019] Preferably, the drive shaft 5 is provided with a number of support bearings 17.

[0020] Preferably, the inner wall of the inner support 14 is provided with several sinkholes 7, which can hold some liquid and continuously absorb heat.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0022] Although this document frequently uses terms such as mounting housing 1, stator 2, bearing A 3, rotor 4, drive shaft 5, bearing B 6, countersunk hole 7, heat dissipation spokes 8, mounting rod 9, sealing plate 10, spoiler 11, connecting rod 12, opening 13, inner support 14, outer shell 15, injection hole 16, support bearing 17, and drainage hole 18, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
